根据野外观察及海域等有关资料的综合分析,本文提出:中国东南大陆边缘地区及毗邻海域,新华夏系显著的区域性构造特征可概括为两点:第一,大陆边缘地区的新华夏系构造是一组平行海陆边界的弧形构造带;第二,大陆边缘地区存在一组北略偏东的构造形迹,其形成时间与弧形构造带相近。大陆边缘地区这一构造特点是在大陆相对海洋运动时,受海陆边界形态的制约而形成的。计算得到的挠度特征及泥板模拟实验结果,有力的支持了上述构造形态成因的理论推断。
Based on the comprehensive analysis of field observations and relevant data, this paper proposes that the significant regional tectonic features of the Neo-Huaxia System can be summarized as follows: First, the Neo-Huaxia structure on the margin of the continental margin Is a group of arc-shaped tectonic belts parallel to the sea-land boundary. Second, there are a group of north-easterly structures in the marginal area of the continental margin, forming similar to the arc-shaped structural belt. This tectonic feature on the fringe of the continental margin was formed when the continent moved relative to the ocean and was conditioned by the shape of the land-sea boundary. The calculated deflection characteristics and the simulation results of mud slab strongly support the theoretical inference of the above causes.
